Specification of Letters Patent.

Patented April 17, 1906.

Application filed October 26, 1905. Serial No. 284.503.

To all wham it nut-y concern:

Be it known that I, WILLIAM H. BooTH, a citizen of the United States, residing at Atkinson, in the county of Fender and State of North Carolina, have invented a new and useful Sliding-Door Fastener, following is a specification.

This invention relates to sliding-door fasteners, more particularly to fasteners employed upon freight-car doors, and has for its object to improve the construction and increase the efficiency of devices of this character.

With these and other objects in view, which will appear as the nature of the invention is better understood, the invention consists in certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating characters, is illustrated the preferred form of embodiment of the invention capable of carrying the same into practical operation, it being understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention within the scope of the appended claims.

In the drawings, Figure 1 is a side elevation. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a perspective view of the sliding bolt detached. Fig. 4 is a perspective view of the lock-casing detached.

The improved device comprises in general a casing having means for attachment to the door-jamb and containing a movable catch and a frame having means for attachment to the door and provided with a slidable bolt adapted for entering the casing on the jamb and being engaged by the catch within the casing.

The casing member of the device is formed with a relatively large transverse aperture 11, extending entirely therethrough, and with an aperture 39 leading through one end and communicating with the transverse aperture 11, the casing being alike on both sides, so that it can be readily reversed in position, and provided with transverse holes 12 to receive the holding bolts or screws.

Piercing the upper side of the casing 10 is a longitudinal slot 13, the slot intersecting the aperture 11, and pivoted at 14 in the casing and operating 1n the slot is a latch member of which the 15, having a lug 16 projecting into the aperture 11, where the latch is closed. The latch member is also provided with laterally-extending stop-lugs 17 for bearing upon the upper face of the casing 10 and limiting the downward movement of the latch and with a lifting-lug 18 to assist in releasing the latch when required.

The lugs 17 are pierced, as at 19, and the portion of the casing opposite the lugs when the latch is closed, as in Fig. 1, are likewise pierced, as at 20, to receive the bolt of a padlock, seal-wire, or slmilar securing means, 1f

required. The .casing 10 is also provided with an aperture 21 to receive a sealing-wire, and thus increase the security of the device. The frame member 22, which is attached to the door, is provided with spaced side ribs 23 24 and with spaced apertures 25 between the ribs to receive the holding-bolts. The side ribs 23 24 are coupled at the outer ends by a band 26 to form a handle by which the door may be moved in opening and closing. Slidably disposed between the guide-ribs 23 24 is a bolt 27, having arecess 28 near one end to receive the lug 16 of the latch 15, and with a longitudinal slot 29, the latter provided with inwardly-projecting guide-ribs 30 31, disposed centrally of the side faces of the bolt. Attached, as by screw-studs 32 and nut 33,,to the frame 22 is a stop-lug 34, provided with shoulders 35 36, bearing over the guide-ribs 30 31. By this means the bolt 27 is held in position between the guide-ribs 23 24 of the frame and free to move therein within the range of the slot 29 to project the recessed bolt into and to withdraw it from the casing 10. The bolt 27 is provided with an operating-lug 37', having threaded stud 38, engaging a threaded aperture extending entirely through the bolt, so that the lug may be inserted from either side.

The parts when connected and assembled, as shown in Figs. 1 and 2, are adapted for a right-hand door; butif it is desired to attach the device to a left-hand door it is only necessary to detach the lugs 34 37, reverse the bolt 27, and restore the stop-lug to its place and insert the stud 38 of the lug 37 into the opposite side of the bolt. The casing 10 and its pivoted latch 15 being alike on both sides, it is immaterial which side is presented to the face of the jamb. By this means itis obvious that a simply-constructed lock is provided, which may be inexpensively manufactured, is strong and durable, and can be readily adapted for use upon all the different styles and forms of cars manufactured, and can be readily reversed in position to adapt it to right or left hand doors without change of structure or modifications in any of the parts.

Having thus described the invention, what is claimed is- 1. In a look of the class described, a frame having means for attachment to a door and provided with spaced longitudinal guideribs, a bolt slidable upon said frame and be tween said guide-ribs and provided with a transverse recess near one end and with a longitudinal transverse slot, the inner faces of said slot having guide-ribs disposed interme diate the side faces of the bolt, a stop-lug detachably connected to said frame and ex tending through said slot and provided with projections engaging the guide-ribs in the same, and whereby the bolt is reversibly disposed upon the frame, a casing having means for attachment to the doorjamb and with an aperture for receiving the free end of the bolt when projected, and a latch swinging in said casing and provided with a lug for engaging the recess in said bolt.

2. In a lock of the class described, a frame having means for attachment to a door and provided with spaced longitudinal guideribs, a bolt slidable upon said frame and between said guide-ribs and provided with a transverse recess near one end, means for detachably connecting said bolt movably between said guide-ribs, a casing having means .for attachment to a door-jamb, and provided with a transverse aperture extending entirely through the same and with a longitudinal aperture communicating with the transverse aperture and an end aperture in the path of and adapted to receive the bolt and a latch swinging through said longitudinal aperture and provided with a lug for engaging the recess in the bolt when the latter enters the casing.

3. In a lock of the class described, a bolt having means for movably connecting to a door and with a transverse recess near the free end, a casing having means for attachment to a door-jamb and with an aperture extending entirely through the same, and with a longitudinal aperture communicating with the transverse recess and an aperture in the end of the casing also communicating with the transverse recess and adapted to receive said bolt when projected and a latch swinging through said longitudinal aperture and provided with a lug for engaging the recess in said bolt and with lateral lugs for bearing upon the casing and limiting the movement in one direction.

In testimony that I claim the foregoing as I my own I have hereto affixed my signature 1n the presence of two witnesses.
